Yes
It is possible. Just keep the drawing instrument 15.915 cm from a set point (the circle's center).
Radii are always positive. No, it is not possible to draw a circle with negative radius.
There are an infinite number of possible chords in anycircle, regardless of its diameter. A chord is a line segment with its endpoints on the curve (circumference) of the circle. You can draw those all day and never draw the same one twice.
Use a pair of compasses to draw a circle. Without changing the compasses, place the point of the compasses on the circumference and draw a small arc such that it intersects the circumference. Put the point on this intersection and repeat until you have 6 equally spaced "intersections". Select 2 adjacent intersections and, from each of them, draw an arc outside the circumference such that the 2 arcs intersect. Draw a line from this intersection to the centre of the circle. This line intersects the circumference halfway between the adjacent points. With the compasses set to the original radius of the circle (it's better to leave them fixed at this throughout!) place the compasses' point on the intersection of the straight line and the circumference then draw a series of arcs, as you did originally. These will complete the division by 12
An arc is a portion of the circumference of a circle, and the circumference of a circle is the distance round a circle. So an arc looks like a semicircle, it is part of the circumference. Arcs are often used in constructions, for example if you were asked to draw an angle of 60 degrees without a protractor you would draw arcs following a special method. Arcs are drawn using a tool called a pair of compasses.
No, the circumference divided by the radius will always be pi for a circle.

Yes
Yes, you can draw a circle with a circumference of 33 centimeters. To find the radius, you can use the formula for circumference, ( C = 2\pi r ). Rearranging this gives ( r = \frac{C}{2\pi} ), which calculates to approximately 5.25 centimeters. Using this radius, you can accurately draw the circle.
Draw two diameters of the circle and join the points where they meet the circumference.
Radii are always positive. No, it is not possible to draw a circle with negative radius.

Draw a circle using a compass. Then, without changing the compass setting, place its point on the circumference of the circle, at any point A, and draw two arcs to intersect the circumference at B and C. Move the compass to B and draw another arc to intersect the circumference at D; and then from C to E. ADE will be an inscribed equilateral triangle.
-- Draw a circle. -- Put a mark at the center, and draw a line across the whole circle through the center. -- Measure the length of the curved line all around the circle. (called the "circumference" of the circle) -- Measure the length of the straight line across the circle. (called the "diameter" of the circle) If you divide the circumference by the diameter, the result is 'pi'. It doesn't matter how big or how small the circle is. The result is always the same.
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
